Preparation and application of low-air-entraining TPEG polyether macromonomer
The invention relates to the technical field of polycarboxylic acid water reducer macromonomers, in particular to preparation and application of a low-air-entraining type TPEG polyether macromonomer, and the low-air-entraining type TPEG polyether macromonomer mainly comprises the following components in parts by mass: 10-20 parts of organopolysiloxane, 1-5 parts of an emulsifier, 2-10 parts of a thickener and 60-80 parts of a solvent. The emulsifier is one or a combination of more of sorbitan monostearate, sodium lauryl sulfate, polyoxyethylene ether, polyvinyl alcohol and sorbitan monooleate; the thickening agent is one or a combination of several of carboxymethyl cellulose, sodium polyacrylate, tragacanth, sodium starch phosphate, hydroxypropyl methyl cellulose and sodium alginate; wherein the solvent is water, and the low-air-entraining type TPEG polyether macromonomer disclosed by the invention has the following beneficial effects that the low-air-entraining type TPEG polyether macromonomer researched by the invention is small in adding amount of a defoaming agent, stable, efficient, high in economic benefit, easy to meter and simple and convenient to operate; redundant large bubbles in the concrete can be eliminated, proper small bubbles are reserved, the strength of the concrete is enhanced, and the surface of the concrete is more attractive.
本发明涉及聚羧酸减水剂大单体技术领域，特别涉及一种低引气型TPEG聚醚大单体的制备及应用，其质量份计主要成分组成包括：有机聚硅氧烷10～20份，乳化剂1～5份、增稠剂2～10份、溶剂60～80份；乳化剂为山梨糖醇酐单硬脂酸酯、月桂醇硫酸钠、聚氧乙烯醚、聚乙烯醇、山梨醇酐单油酸酯中的一种或几种组合；增稠剂为羧甲基纤维素、聚丙烯酸钠、黄芪胶、淀粉磷酸酯钠、羟丙基甲基纤维素、海藻酸钠中的一种或几种组合；其中，所述溶剂为水，本发明具有以下有益效果：本发明研究的低引气型TPEG聚醚大单体，消泡剂添加量少，稳定高效，经济效益高，易计量操作简便；可以消除混凝土中多余的大气泡，保留适当的小气泡，增强混凝土的强度并使混凝土的表面更为美观。
